Abstract

Direct-write assembly of a three- dimensional periodic structure comprised of hexagonal filaments is demonstated. The structure is created by robotically depositing a concentrated colloidal gel-based ink through a cylindrical deposition nozzle modified by attaching a UV-LIGA (lithography, electroplating, and molding)-fabricated hexagonal micro (μ)-tip that controls filament geometry.
